Arsenic As MicroTrace Minerals

Inorganic arsenic occurs naturally in soil and in many kinds of rock especially in minerals and ores that contain copper or lead When these ores are heated in smelters most of the arsenic goes up the stack and enters the air as a fine dust Smelters may collect this dust and take out the arsenic as a compound called arsenic trioxide As 2 O 3
